The structure of a sentence largely depends on how it fits into the broader context of discourse. This is reflected, for example, in the choice of word order, intonation, or the selection of certain lexical means. These means form the informational structure of the sentence. The topics covered in this book are useful in many areas of linguistics: they particularly help to uncover stylistic nuances in texts, understand peculiarities of spoken language, or categorize certain aspects of language acquisition. Knowledge of informational structure can assist German teachers in understanding why some sentences from their students sound odd and seem to not quite fit into the context. The book can serve as a foundation for introductory courses.
